I wondered if anyone on here has considered making there own.I have managed to see one picture of a unit which is this below,
http://www.stonehealth.com/uncategorised/a-successful-trial-with-a-doff-in-an-unusual-setting/
It seems to be a revered system but I know nothing about them.Surely it can`t be actually magic !
Am looking for any helpful info at all,regards.

Its an electric pressure washer. Low psi/flow and high heat. Chris will be along shortly to tell you what you need to make one. The problem lies in the hoses/fittings/o ring etc that go along with using 150 - 160 degree heat/steam

15-17 secs of this video shows the red doff parked next to a petrol washer.

I read on the stonehealth site that servicing includes a new ceramic nozzle and safety valve. I dont fancy standing next to a diy one if it goes pop!
How much are they? My hunch for a full set up is £6k plus and that it might be possible to assemble something equal at £3k using new.

Glorified hotbox.
Stonehealth dress it up like it will pull carbon out of stone and off accy brick

As much as i think stonehealth talk it up, its the TORC system that they say will remove carbon. The DOFF is used for vegetation etc..

used to be a kranzle k7/120 run through a 21 litre hotbox to get 150 degrees steam but now I think they use what looks like an interpump. they are very sneaky by selling a machine for 6K that can be built by anyone and never taking full on pictures so no one can see what pump it is ;D

A Honda GX160 5.5HP,Interpump AT 11 L/MIN might suffice then,150 bar though.Turn it down a little I guess.This is coupling it with a 21 litre hot box.
Reason for wanting it- Monocouche render,large appt block,,no chems,nasty staining from individual appts run off from balcony decking and metalwork and black staining coming down from roof line which I think is some sort of oxidation run off. I can`t offer clean and repaint so looking for the clean to excel.

Do a test first...I think you will struggle even with steam. Do you have pictures?

The very first picture top left is ground level,i scrubbed it with a high alkaline general cleaner and didn't make any impression at all.

Done a few of these pal and not mastered them. If our client wanted to proceed into complete removal I'd have given them more attention but they were happy. I was also thinking along the line of an oxidisation, preferably from the galvanised steel. We tried Oxalic, no change.

The black streaks are fungus thought to be a form of Cladosporium spp or Alternaria spp ...a mold .
Only chemical cleaning will remove it. As it "stains" the surface
They are not a "metallic run off, either from bolts or framework"!! The roof copings look like stone .
The walk ways/patio's and their fitting and fixtures are galvanised and stainless steel ;D
"match up the paint colour and go in with the offer to repaint specific areas" Do not get involved in that.
